Match the Column I with Column II and select the correct answer by given codes.

Codes

Options

A. `{:(A,B,C,D),(2,4,3,1):}`
B. `{:(A,B,C,D),(2,4,1,3):}`
C. `{:(A,B,C,D),(4,2,3,1):}`
D. `{:(A,B,C,D),(4,2,1,3):}`

Explanation

`A rarr 2, B rarr 4, C rarr 1, D rarr 3`
A. `Li^(+)lt Al^(3+)lt Mg^(2+)lt K^(+)`
The cation with the greater positive charge will have a smaller radius because of the greater attraction of the electrons to the nucleus. Anion with the greater negative charge will have the larger radius.
Positive charge `prop (1)/("ionic radius")`
Negative charge `prop` ionic radius
B. Greater positive charge, increases ENC in case of isoelectronic species while for same group elements, ENC decreases down the group.
C. `Cl gt F gt Br gt I`
Electron affinity of Cl is highest in halogen family.
D. `F gt Cl gt Br gt I`
Electronegativity of fluorine (F) is higher than that of Cl, Br and I.
